The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.

Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.

Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

Shipping Weight

The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width &amp; height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

Discussion: Peak K2 is menatetrenone (MK-4), a form of vitamin K2 made in the body form phylloquinone (vitamin K1) and distinct from the menaquinones made by probiotic bacteria. Available science indicates that vitamin K2 — and especially menatetrenone — is superior to Vitamin K1. Clinical trials have shown that high-dose vitamin K2 does not cause excessive or abnormal blood clotting, although it will interfere with "blood thinning" medications.

Very effective. If you combine it with vitamin D you can feel your teeth getting cleaner within a few days. Very good for your bone density and for keeping plaques away from your arteries. Great product.

I've been taking this product for years. I was quite happy with it. However, I now noticed the price at Amazon and was surprised to see the price is a lot lower. I'm a bit disappointed since I have blindly ordered with Iherb the past years trusting their prices were competitive.

For the money, this is a great deal because the dosage is high. Also, it is menatetrenone, the most active form. I like that it's non-soy. Just FYI, stop taking it at least 10 days before seeing a dentist because your gums will bleed and your dentist will think you have a gum problem.

Recommended by my doctor, who is currently doing K2 MK-4 research with rodents. The rodents live up to 50% longer.

My thyroid went out over the winter due to cold, dry air setting off my allergies (uses up zinc rebuilding damaged mucous membranes and zinc is needed for the thyroid), and when you go even subclinically hypothyroid (TSH >=2.0) your cholesterol starts to rise as mine did. My bp went up and as spring came it did not recover...obviously the blood vessels got clogged. I took this product on alternate days with a natto product from Drs Best (they are both blood thinners so I decided to alternate days) and in about 2 weeks I felt better and my blood pressure improved significantly. (To me that is FAST!). This is also used in Japan for osteopenia. But only in THIS (MK-4) form...it is toxic to take MK-7 in high dose (I believe). This product is the highest dose I could find MK-4 in and it is 1/3 the dose they give in Japan for osteopenia(I believe). I wouldn't take it is a higher dose when this dose works so well.
